Motion detection device and method, luminance/chrominance signal separation device and method, noise reduction device and method, and video display device and method
First Claim
1. A motion detection device comprising:
- an oblique correlation detection section for detecting an oblique correlation of a composite video signal;
a motion detection section for detecting a motion amount based on an inter-frame difference of the composite video signal; and
a motion determination section for determining the presence of a motion in the composite video signal based on the motion amount detected by the motion detection section, wherein the motion determination section determines the presence of a motion considering the detection results of the oblique correlation obtained by the oblique correlation detection section.

Abstract
The motion detection device includes an oblique correlation detection section, a motion detection section and a motion determination section. The oblique correlation detection section detects a correlation in an oblique direction (oblique correlation) of a composite video signal. The motion detection section detects a motion amount based on an inter-frame difference of the composite video signal. The motion determination section determines the presence/absence of a motion in the composite video signal based on the motion amount detected by the motion detection section. The motion determination section determines the presence/absence of the motion considering the detection results of the oblique correlation by the oblique correlation detection section.
